Andy Baio from Waxy.org was intrigued by his initial experience with Amazon’s Mechanical Turk, and wanted to know more about the people that participate in the service, including what they look like, and how much it would cost for them to reveal their faces.

To make the process easy, he fired up the Mechanical Turk and added a simple task to the queue: Upload a photo of yourself holding a handwritten sign that says “I Turk for…”, filling out why you turk.

At $.05 per photo, there wasn’t much response, but at $.25, the responses started to come in, and by $.50, he had a decent sized sample.

The results? 30 people total – 20 men and 10 women, almost all of which were white and in their 20s and 30s. 21 turk for money, and the other 9 turk for fun or boredom.
